From 3b2ebeaf98a028d5dd4ec63095855ef507920276 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Wed, 24 Feb 2021 12:06:35 -0800 Subject: mm/gfp: add kernel-doc for gfp_t The generated html will link to the definition of the gfp_t automatically once we define it. Move the one-paragraph overview of GFP flags from the documentation directory into gfp.h and pull gfp.h into the documentation. This generates warnings with clang (https://lkml.kernel.org/r/20210219195509.GA59987@24bbad8f3778), so use a #if 0 to hide it from the compiler for now.
